LABEL ATTACHING APPARATUS, LABEL ATTACHING METHOD, AND PROGRAM

1 . A label attaching apparatus for attaching a label to an adherend, comprising:

a measurement unit configured to measure a shape of the adherend; and

an attachable region determination unit configured to determine an attachable region of the label on the adherend based on the shape.

2 . The label attaching apparatus according to claim 1 , wherein

the measurement unit measures the shape by using a parameter based on a height of the adherend from a placement surface on which the adherend is placed, and

the attachable region determination unit determines a region in which the parameter is equal to or greater than a threshold value as the attachable region.

3 . The label attaching apparatus according to claim 2 , wherein

the attachable region determination unit sets, as the threshold value, a value obtained by subtracting a predetermined value from a highest value of the height of the adherend from the placement surface.

4 . The label attaching apparatus according to claim 1 , wherein

the attachable region determination unit determines a position at which the label is attached with reference to a center of the attachable region.

5 . The label attaching apparatus according to claim 4 , wherein

the attachable region determination unit determines the position at which the label is attached such that the center of the attachable region corresponds to a center of the label.

6 . The label attaching apparatus according to claim 1 , further comprising:

an adherend conveying unit configured to individually and continuously convey a plurality of the adherends;

a label conveying unit configured to individually and continuously convey a plurality of the labels; and

a label holding unit configured to pick up the label conveyed by the label conveying unit with an adhesive surface thereof facing an adherend side, wherein

the measurement unit is configured to measure a shape of each of the adherends, and

the attachable region determination unit is configured to determine the attachable region of the label on the adherend based on each shape, and

attach the label picked up by the label holding unit to the attachable region.

7 . The label attaching apparatus according to claim 6 , further comprising:

a downstream side detection unit configured to detect the label attached to the adherend, wherein

in a case where the label on the adherend is not detected by the downstream side detection unit, an unattachable label is attached to an adherend to be conveyed next to the adherend to which the label is not attached.

8 . The label attaching apparatus according to claim 6 , further comprising:

a downstream side detection unit configured to detect the label attached to the adherend, wherein

in a case where the label on the adherend is not detected by the downstream side detection unit, an unattachable label is discarded in a discarding region provided at a position different from the adherend conveying unit.

9 . The label attaching apparatus according to claim 6 , wherein

in a case where the attachable region determination unit cannot determine the attachable region on the adherend, the adherend is caused to retract to an outside of the label attaching apparatus without attaching the label to the adherend for which the attachable region cannot be determined.

10 . The label attaching apparatus according to claim 6 , further comprising:

a printing unit configured to execute printing on the label, wherein

the label subjected to printing by the printing unit is attached to the adherend.

11 . The label attaching apparatus according to claim 6 , wherein

the label holding unit is formed to be stretchable in an attachment direction in which the label is attached to the adherend.

12 . A label attaching method for attaching a label to an adherend, comprising:

measuring a shape of the adherend to be conveyed;

determining an attachable region of the label on the adherend based on the shape; and

attaching the label to the attachable region.

13 . A program executable by a computer of a label attaching apparatus for attaching a label to an adherend, the program causing the computer to execute:

a procedure of measuring a shape of the adherend to be conveyed; and

a procedure of determining an attachable region of the label on the adherend based on the shape.
